[QUOTE="Simon_49, post: 462213, member: 14233"] As stated in one of the above posts, measuring the resistance isn't going to be a reliable method of determining whether what you found is gold or not, most metals usually do have an electrical resistance lower than about 0.1 ohm, even Aluminium, and you also have to take into account the electrical resistance of the copper in the multimeter probe wires, a typical digital multimeter has an input impedance of 10M, or ten million ohms.
